Flipping Gravity. Is it possible?

Hey so I’m making a infinite runner and I have been very successful for solving majority of my problems. However after looking through a lot of the threads, I don’t think this has been attempted before. Can it? Or is it possible to flip platform gravity?

If your using the platform automatism then you can use the action “Gravity” in the platform automatism actions and set it to -100 or whatever speed you want it to be.
